[0001] This invention relates to the field of medical waste treatment cutting tools, specifically a combination cutting tool. Background Technology

[0002] In the existing technology, medical waste needs to be crushed during treatment. However, the crushing blades in the existing technology cannot crush medical packaging bags, resulting in incomplete crushing. Furthermore, medical waste is prone to accumulation, affecting the processing efficiency. Therefore, there is a need for improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a combined cutting tool to solve the problems mentioned in the background art.

[0004] The present invention proposes a technical solution: a combined cutting tool, disposed in a receiving cavity for medical waste treatment, for medical waste crushing treatment, including a main cutting blade assembly and several auxiliary cutting blades. The main cutting blade assembly is disposed at the bottom of the receiving cavity, and the central axis of the main cutting blade assembly coincides with the central axis of the receiving cavity. The several auxiliary cutting blades are spaced apart on the inner sidewall of the receiving cavity, and the cutting parts of the several auxiliary cutting blades are horizontally oriented towards the main cutting blade assembly.

[0005] The main cutting blade assembly includes a plurality of first blades and a plurality of second blades. The cutting edge of each first blade is arranged in a horizontal direction, and the cutting edge of each second blade is arranged in a vertical direction. The first blades are positioned below the second blades in a vertical direction.

[0006] The main cutting blade assembly also includes a mounting base for connecting a drive component. A connecting post is provided on the side of the mounting base away from the drive component. A stepped surface is provided between the connecting post and the mounting base. A first blade holder is provided on the stepped surface. The first blade holder includes a connecting part and a mounting part. Two mounting parts are respectively provided on both sides of the connecting part. The mounting part is used to mount the first blade. The connecting part is detachably connected to the mounting base.

[0007] The main cutting blade assembly also includes a second blade holder, which is disposed on the side of the connecting portion away from the mounting base, and is used to mount the second blade.

[0008] The second tool holder is frustum-shaped, and the upper end of the frustum is provided with a notch. The second tool includes a connecting rod and vertical blades provided at both ends of the connecting rod. The connecting rod is located at the notch.

[0009] The connecting part has a first connecting hole for connecting to the mounting base, and the connecting part is fixedly connected to the mounting base by a first fastener; the mounting part has a second connecting hole for mounting the first tool, and the first tool is connected to the mounting part by a second fastener.

[0010] A washer is also provided between the second tool holder and the connecting part.

[0013] The first cutting tool has several third connecting holes, which correspond to the second connecting holes.

[0014] This invention provides a combined cutting tool with the following improvements and advantages compared to the prior art:

[0015] The main cutting blade assembly is positioned at the center of the receiving cavity, meaning its central axis coincides with the cavity's central axis. This prevents medical waste from accumulating in the center during cutting. As the main cutting blade assembly rotates and cuts, centrifugal force throws the medical waste against the cavity's sidewalls, allowing it to be further cut by the secondary cutting blades. Since the secondary blades face the main cutting blade assembly, they can effectively break down and cut even small gaps in the medical waste, ensuring thorough fragmentation. Furthermore, the main cutting blade assembly, during rotation, works in conjunction with the cavity's sidewalls to rub against the medical waste, thus achieving frictional heat sterilization.

[0022] Figure 6 for Figure 5 Sectional view at point AA. Detailed Implementation

[0023] The core of this invention is to provide a combined cutting tool to solve the problems mentioned in the background art.

[0024] The following will be combined with the appendix Figures 1 to 6 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] It should be noted that the terms "first" and "second" used in the embodiments of the present invention are for descriptive purposes only and should not be construed as indicating or implying the number of technical features defined therein. Therefore, features defined with "first" and "second" in the embodiments of this specification can indicate that at least one of the defined technical features is included.

[0026] The technical solutions of the various embodiments of the present invention described in this specification can be combined with each other, but only if they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that the combination of technical solutions does not exist.

[0027] like Figure 1-6 As shown, the present invention proposes a technical solution: a combined cutting tool, disposed in a receiving cavity for medical waste treatment, for medical waste crushing treatment, including a main cutting blade assembly 100 and several auxiliary cutting blades 6. The main cutting blade assembly 100 is disposed at the bottom of the receiving cavity, and the central axis of the main cutting blade assembly 100 coincides with the central axis of the receiving cavity. The several auxiliary cutting blades 6 are spaced apart on the inner sidewall of the receiving cavity, and the cutting parts of the several auxiliary cutting blades 6 are horizontally oriented towards the main cutting blade assembly 100.

[0028] In an embodiment of the present invention, the main cutting blade assembly 100 is positioned at the center of the receiving cavity, meaning the central axis of the main cutting blade assembly 100 coincides with the central axis of the receiving cavity. This prevents accumulation of medical waste in the center of the receiving cavity during cutting. As the main cutting blade assembly 100 rotates and cuts, centrifugal force throws the medical waste toward the side wall of the receiving cavity, allowing it to be cut again by the secondary cutting blade 6. Since the cutting part of the secondary cutting blade 6 faces the main cutting blade assembly 100, it can break and cut small-gap medical waste with the assistance of the main cutting blade, thus thoroughly breaking and cutting the medical waste. Furthermore, during rotation, the main cutting blade assembly 100, in conjunction with the side wall of the receiving cavity, rubs against the medical waste, thereby performing frictional heat sterilization on the medical waste.

[0029] In one embodiment of the invention, the main cutting blade assembly 100 includes a plurality of first blades 101 and a plurality of second blades 102, wherein the cutting edge of each first blade 101 is arranged in a horizontal direction, and the cutting edge of each second blade 102 is oriented in a vertical direction, and the first blades 101 are disposed below the second blades 102 in a vertical direction.

[0030] In this embodiment, the blade of the second cutter 102 is arranged vertically, which allows the second cutter 102 to break the outer packaging of medical waste during the rotational cutting process, and under the action of centrifugation, it can turn the medical waste outward, so that it can be further cut by the first cutter 101. The blade of the first cutter 101 is arranged horizontally, which allows the blade of the first cutter 101 to be positioned opposite the cutting part of the secondary cutter 6, so that the first cutter 101 and the secondary cutter 6 can cooperate with each other during the cutting process. Therefore, when the first cutter 101 is facing the secondary cutter 6 during rotation, the first cutter 101 can cooperate with the secondary cutter 6 to break and cut small medical waste; when the first cutter 101 is not facing the secondary cutter 6, it can break and cut larger and harder medical waste. This allows the present invention to cut and break various types of medical waste, improving the practicality of the present invention.

[0031] In one embodiment of the present invention, the main cutting blade assembly 100 further includes a mounting base 1 for connecting a driving component. A connecting post 11 is provided at one end of the mounting base 1 away from the driving component. A stepped surface is provided between the connecting post 11 and the mounting base 1. A first blade holder 2 is provided on the stepped surface. The first blade holder 2 includes a connecting part 21 and a mounting part 22. Two mounting parts 22 are respectively provided on both sides of the connecting part 21. The mounting part 22 is used to mount the first cutting blade 101. The connecting part 21 is detachably connected to the mounting base 1.

[0032] In this embodiment, by setting a mounting base 1, which is connected to an external driving component, and connecting the first tool 101 to the mounting base 1 via the first tool holder 2, the installation of the first tool 101 is facilitated. The mounting base 1 has a stepped surface, and the first tool holder 2 is mounted on the stepped surface, thereby improving the compactness of the overall structure. The mounting part 22 is set on both sides of the connecting part 21, and the first tool 100 is fixed on the mounting part 22. Several first tools 100 are connected to the mounting part 22 by multiple fasteners, thereby improving the cutting performance of the first tool 100.

[0033] In one embodiment of the present invention, the main cutting blade assembly 100 further includes a second blade holder 3, which is disposed on the side of the connecting portion 21 away from the mounting base 1. The second blade holder 3 is used to mount the second blade 102. The second blade holder 3 is frustum-shaped, and a notch 31 is provided at the upper end of the frustum. The second blade 102 includes a connecting rod 51 and vertical blades 52 disposed at both ends of the connecting rod. The connecting rod 51 is disposed at the notch 31. A first connecting hole 211 for connecting the mounting base 1 is provided on the connecting portion 21. The connecting portion 21 is fixedly connected to the mounting base 1 by a first fastener 23. A second connecting hole 221 for mounting the first blade 101 is provided on the mounting portion 22. The first blade 101 is connected to the mounting portion 22 by a second fastener 24. The second blade 102 is fastened to the second blade holder 3 by a third fastener 53. The second blade holder 3 is connected to the driving component by a fourth fastener 32.

[0034] Furthermore, in this embodiment, the second blade holder 3 abuts against the connecting part 21, and the fastener is fastened to the rotating shaft 8 on the drive component through the central hole on the connecting post 11. Thus, the second blade holder 3 and the first blade holder 2 are coaxially arranged, thereby causing the first blade 101 and the second blade 102 to rotate coaxially to cut the medical waste. This allows the medical waste, after being crushed by the second blade 102, to be further crushed by the first blade 101.

[0035] In one embodiment of the present invention, a washer 36 is further provided between the second tool holder 3 and the connecting part 21.

[0036] In this embodiment, a washer 36 is provided between the second tool holder 3 and the connecting part 21, so that the second tool holder 3 will not wear with the connecting part 21 during operation, thereby improving the service life of the second tool holder 3.

[0037] In one embodiment of the present invention, the head of the fourth fastener 32 is provided with a locking member 33.

[0038] By providing a locking member 33 at the head of the fourth fastener 32, the locking member 33 is sleeved on the head of the fourth fastener 32, and the fourth fastener 32 is a hexagonal bolt. The inner ring of the locking member 33 is provided with multiple slots, which engage with the edges and corners of the hexagonal bolt. This ensures that the fourth fastener 32 will not loosen due to vibration during operation, thereby improving the stability of the invention.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
